Perhaps some do, but generally speaking this is unnecessary for spyware
to exist, as I said before; spyware exists regardless of such
vulnerabilities.

A user can install spyware with one click for the same reason he can
install a *good* application with one click. Having the user run every
day with install privileges is relatively irrelevant; if he owns the
machine, he will have the ability to install things. Being prompted for
an admin password (as in the case of OSX) hardly prevents a stupid user
from installing crap.

How do you intend to make spyware not install while still allowing the
user to install other things?

See above.

I cannot do so from "clicking randomly," but I quite easily can simply
from clicking "OK" to the download prompt. Firefox installs plugins and
toolbars just as easily as IE does.

So we don't give the *owner* admin privileges? Mac does this, as does
Linux. I don't know of a single OS where the machine's owner does not,
by default, have admin access.

Of course. But the ability to execute code is pretty much
non-negotiable. I will never buy a general purpose PC on which I cannot
run programs of my choosing. And if MS sold one as such, you would be
here complaining about that instead. 

The point is, spyware does not require OS vulnerabilities to be spyware,
and it likely, for a long time to come, never will. I never argued that
Windows is the most secure OS, however, only that spyware does not imply
bugs. And that point should, by now, be crystal clear.
